Foam Ball Pigs

Foam Ball Pigs, like Foam Squeegees, are available in numerous configurations: • Fully Coated: Completely coated with polyurethane to improve wear resistance and seal.

  • Criss Cross Coated: Mostly coated with polyurethane in a criss-cross pattern to improve scraping and cleaning action.
  • Criss Cross Wire Brush: Mostly coated with polyurethane in a criss-cross pattern, plus strips of wire brush for an aggressive cleaning pig.
  • Silicone Carbide Coated: Completely coated with polyurethane, including embedded silicone carbide grit for an aggressive cleaning pig.
  • Bare: Uncoated foam. All foam pigs are available in medium density (5-7 lb/ft3) or hard density (8-10 lb/ft3). Sizes up to 8.5” (in 0.25” increments) are always in stock. Custom densities available upon request.

Foam Swabs

Foam Swabs are made from lightweight (1-3 lb/ft3) open-cell polyurethane foam that is very porous and acts like a sponge to wick up liquids. They are mainly used in new pipeline construction during the drying phase, may be used to dry out operational lines in order to help meet dew point requirements, and are often used in municipal service (water and sewer lines). Foam Swabs are relatively low-cost items, typically with a simple cylindrical shape. As a standard measure to improve propulsion down the pipeline, we apply a polyurethane coating to the back of our Foam Swabs. Because of their low density, Foam Swabs have much lower wear resistance than our other foam and polyurethane products, and are often only good for one trip down the pipeline.


  • Available densities range from 1.2 lbs/ft3 to 3 lbs/ft3. Contact one of our technical advisors to discuss the best density for your application.
  • Tapered noses are available upon request.
  • Foam Swabs are available without the rear coating of polyurethane, upon request.
  • Pull Ropes and wood plates can be installed on large-diameter Foam Swabs (greater than 16”) to make handling easier. Note that it is very common to oversize swabs by 1-2” (or more, in the case of lines with diameters greater than 16”) above the pipeline inside diameter due to their extreme compressibility

Foam Squeegees

We manufacture a wide variety of Foam Squeegees. Depending on the model chosen, Foam Squeegees can be used for dewatering and fluid removal, light to heavy wiping, and aggressive scraping and cleaning. Various sizes, shapes, foam types, and coatings are available, allowing you to design the optimal product for your needs. Four details need to be determined before placing a Foam Squeegee order:

  1. Size: The exact diameter of the required Foam Pig must be specified. This will be dependent on the Nominal Pipe Size, wall thickness, and desired amount of oversize.
  2. Shape: Standard Bullet Nose, Double Dish, or Double Nose.
  3. Foam Type: Regular or Hard. Note that foams with custom hardness are available upon request.
  4. Coating: Bare, Criss-Cross Coated, Fully Coated, Criss-Cross Wire Brush, Power Brush, or Silicone Carbide Coated.
